Intestinal gene expression in different physiological conditions There is not condition-dependent expression data available for this gene.
Gene details (from Flybase) It is a protein_coding_gene from Drosophila melanogaster.
Based on sequence similarity, it is predicted to have molecular function: ARF guanyl-nucleotide exchange factor activity.
There is experimental evidence that it is involved in the biological process: positive regulation of multicellular organism growth.
21 alleles are reported.
The phenotypes of these alleles are annotated with: embryonic/larval salivary gland; crystal cell.
It has 3 annotated transcripts and 3 annotated polypeptides.
Protein features are: Pleckstrin homology domain; Pleckstrin homology-type; SEC7-like; SEC7-like, alpha orthogonal bundle.
Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderately high expression to a trough of low expression.
Peak expression observed within 00-06 hour embryonic stages, during early pupal stages, in adult female stages.
